8-2. Look up the IC data sheets, and use maximum values to determine $P_{\mathrm{D}}$ (avg) and $t_{\mathrm{pd}}$ (avg) for one gate on each of the following TTL ICs. (See Example 8-2 in Section 8-3.) $(\mathrm{a})?7432$ (b) $?74\mathrm{S}32$ (c) $74\mathrm{LS}20$ (d) 74ALS20 (e) 74AS20 8-3. A certain logic family has the following voltage parameters: $\begin{array}{rlrl}{V}_{\mathrm{IH}}(\min )& =2.2\mathrm{V}& V_{\mathrm{IL}}(\max )& =0.9\mathrm{V}\\ V_{\mathrm{OH}}(\min )& =3.8\mathrm{V}& V_{\mathrm{OL}}(\max )& =0.4\mathrm{V}\end{array}$ (a) ${}^{?}$ What is the largest positive-going noise spike that can be tolerated? (b) What is the largest negative-going noise spike that can be tolerated?
